Unable To Connect To My Router (Details Below) PLEASE HELP RRS feed

  • Question

  • First of all, let me start out by thanking everyone who replies to this post.

    Okay, so let me begin.

    My devices are configured like so:

    Wall Jack > Line Filter > Modem (Netgear DM111PSP) > Wireless Router (Linksys Cisco Valet M110) > Desktop Computer (Custom Built, Win 7 SP1)

    Around 2 weeks ago I had a thunder storm. I was currently away from home when this happened. When I returned home later that day my internet was out. I proceeded to reset my modem / wireless router / restart my PC. After all this had been accomplished, my internet connection needed to be configured. So I plugged my modem straight into my computer. (Bypassing the wireless router.) I went into my browser to access my modem to configure it and I could not access the modem page. Then I called my ISP (AT&T) and explained to problem. I got transferred to multiple different tech support lines and none of them could give me a steady reply until i got to one support line who said I would have to pay $49.99 to get this problem fixed by them. I am not a very wealthy person, so I began working on this problem by myself. (Might I also add that I am A+ / Strata tm Certified) After many days of working and getting small problems fixed I have a final problem. I configured my modem myself and got the internet connection connected to the modem. I, then, set up my router and have that configured. Now, where the problem lies is, I cannot connect to the modem / router still from my computer. But all of my other devices can. (Laptop, iPod, Xbox 360) (This is Wired / Wireless connections: They both work.) My main desktop cannot connect.

    After investigation, my desktop displays itself having an APIPA address. (169.254.x.y) Which is meaning that it can not connect to the modem. (This is when my modem is directly connected to the computer.) So i thought I would try the Netgear Genie TM software that came with the modem. It displays that there is no Ethernet cable connected / Ethernet driver is disabled, and cannot access the modem. Now, before I go any further, note I have tested the Ethernet cable on my laptop and got a steady connection, and my Network Ethernet controller is installed / enabled. This honestly is making no sense by this point. After this, I go into my CMD as Admin, and run an IPCONFIG /ALL. I get the following:

    *Ignore the COMODO Unite / Hamachi connections. These are 3rd party software.*

    Whenever I try: IPCONFIG /RENEW i get the following message: An error occurred while renewing interface Local Area Connection : Unable to contact DHCP server. Request has timed out.

    I have verified the following:

    The Ethernet cord is good. (Tried on Laptop: Success)

    The NIC is good. (Pinged 127.0.0.1 , Success)

    My Modem is configured correctly and is connected to the internet.

    My Router is configured correctly and can broadcast wireless internet.

    I have tried the following potential fixes offered by forums / tech. support / etc:

    Power Cycling Router

    Turning off Computer / Router / Modem and restarting them.

    Using Modem Installation disk.

    Uninstalling / Re-installing Ethernet Controller

    Disabling Firewalls / Antiviruses

    Calling multiple Tech Support lines

    Commands:

    netsh winsock reset

    netsh int ip reset resetlog.txt

    ipconfig /release

    ipconfig /renew

    ipconfig /flushdns

    A personal note from myself: I honestly am just as confused as the next person. My ethernet cord / modem / NIC are configured fine. I do not see why my computer can not see the connection. Please help. I have spent countless hours working trying to fix this problem.
